" frnitnureron swirciiizocnj Y Ballena, aciti'zen oli' the'United States,fresid' ing at Meriden, inthe county of New Haven andState ofi Connecticut, have invented certain 'new and useful Improvements in Pen mutation Switch Locks; and I do declarethe following to be' aV full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use `the same;

' This invention relates. .to an improved.

lock for use in connection with the switch of an automobile and one object of the invention is to lprovide'a lock having a housing to be secured Aat opposite relation 'to the switch upon the instrument board andhaving a keyv extending through the housing and carrying a switchj' engaging element, permutation means'being pro-vided Ato control lsliding and rotary; 'movement of the plunger lkey.

' Another "object of the invention is to. so construct the permutation-v tumblers and key thatwhen the key `isinan inoperative position with respectto thes'witch, the permutation tumblers may have rotary movement independent of the key'and toV i'urtherl so. construct the key and tumblers that when the key is movedlongitudinally into an op` erative position with yrespect to the switch the tumblers maybe turned with theV key.

lAnother objectofthe invention is to provide improved meansY Afor rotatably mount- V ing the tumblersand slidablyfand rotatably 35 mounting the key, this mounting means servis ing not only to rotatably mount the tumblers but further serving to prevent rotary moves ment of the key when in an inoperative position with respect to the switch and further serving to limit rotary movement of .the key when lnan operative position andprevent longitudinal movement lof the key to infinoperative position after the plunger key has. been turned to move the switch.

Another object of the invention is to provide a klock which will be very compact and will be well protected.4

. Another ob`ect of the invention is to pros vide aV lock in which the partsforming the same canbe easily'taken apart for repairing or changing the combination and then easily putV together again.

This invention is .illustrated in the acs` companying drawings, wherein `Figure lisa view 'in elevation looking at the outer end ofthe lock.

This switch lock isprovided with ahousf ing l whichis provided with `a head ,at its outer end andadjacent its open end is pro,-l vided 'with internally threaded sockets 2 for vreceiving securing bolts which will be passed through the instrument board. will thus be securely but releasably heldin Vengwgenient 'with the instrument ,board with the housing positioned about y the ordinary switch. `The switch will thus be enclosed in the 'combination 'of lockis known. @A block is' 'secured theupperv pontion, @tgt-he' housing lA and carries 'a` ll-shaped tumbler'casing 4, one dependinggarm'ojwhich"'engages the innery face 'of I,the`

and open ends of the housing. 5 and 6 are provided with'openings TY-and `the housing and. cannotbe adjusted unless ico registering with an opening formed in the head of Athe .housing 1 and the openingi 8 being smaller; tongue. 9 extends into the as's'hown in Fig. 14 for a purpose to be hereinafter brought out.

The tumblers l0, 11 and 12'are positioned The tumblers are; each provided' with a pas-vr sage resembling a key-hole open1ng.`

These Vkey-hole passages 1 5 of the tumbler disks will be yenlarged to provide pockets 16 which are circular in shape and of a diameter correspondingr to .the greatest diameter of the key-hole passage. In order to rotatably mount these .tumblers, .there has` been provided a bearingsleeve 17 which I asses through the 'tumblers and havin one D end titting into the opening 8 of the arm 6;

i ina'fter brought out. The tumblers-will ber A notch or recess 18 is provided to receive the tongue 9 and thus provide means to prevent the bearing sleeve from having rotary movement. This bearing sleeve is provided with a longitudinally extending slot 19 and is further cut to provide recessesl 20 which extend `from the sides or'1 theslot 19. It will thus be seen thatl when assembling it issimply necessary to put the tumbler 10 in place and then put they tumblers 11i and 12 in place and pass thefbearingQ sleeve through the` passages "15 of the tumblers until the endof the bearingsleeveits Vinto Y the' opening 8 and the tongue 9 fits into Ithe Vnotch 18.

The tumblers will thus be rotatably mounted and vmay be turned toa desired position. In order to permit'rotary movement to be transmittedr from one tumbler to another, there has been provided pins 21 wliichvwill be brought into contact to impart rotaryV movement as will be hereprovided witha plurality of pin'receiving openings 22 so that by transferrlngthe pins to different openings, the combination may beehanged.

After the tumblers have beennput in place7 the setting block 23 will be putv inplace. This setting block is provided with a passage 24 for registering with the interior of the bearing sleeve 17V as shown in Fig. 2,'

thel passage being enlargedto provide a pocket 25 for* receiving the extended hub extension 14 of the tumbler 10. Securing screws 26 are passed through' openings fformed'in the setting block and screwed into Vthreaded openings orsockets 27 formed in the hub extension 14. These screws securely but releasably connect the setting in F 2. After the setting block has been connected with the hub extension of the tumbler 10', the plunger key 29 will be passed through the passage 24 and through the bearing' sleeve. rfhis plunger key is pros vided with lugs 30 which will pass through the slot19 and may move up intothe recesses 20' when the key is turned. Arblook 31v is secured upon thel plunger key at the Y Y proper distance from` the collarY 32 kso that 75 the plungerkey will be Vpermitted of limited longitudinal movement. `Lugs 33 extend from this block for engaging the switch and turning the same to an adjusted position-y wheny the key is in .the position shown in 8i Fig.2.r, .y

When this lock is yin use, it will'be 'lassembled as shown in F ig. 2 andwill be connected with the instrument board in .operative'relation to the switch bysuitable securingserews passingthrough the instrumentboard and screwed into the threaded sockets 2. Ordinarily, the keyv will be drawn outwardly so that the block 31 moves out o1" engagement with the switchand will be 90 positioned kclose to and preferably in con,- tact with the arms 6 of the tumbler casing 4. Thelugs 30 of the key will thenbe posi# tioned in the pockets 16 ofthe.tumblersfandV the tumblers can be rotated VVto seatteryorv set Ythe combination. Withzthe combination scattered, the key cannot beY moved Yinwardly A to 'engage theswitch and it-,will thus be seenthat the switch cannot lie-turned on Y u nlessthe proper .combination is known.

Vhen setting.V the combination, the setting block will rst be turned vtoward theright in Fig. 1 a number of times and as it turnsv the pin 21 of the tumbler 10 will iirstfengage the co-operating pinV of theV tumbler 1'1A thus turning the tumbler 11 withVV it and eventually bringing the second pin 21 of this tumbler 11 into engagementwith the pin of the tumbler 12.*` The three tumblers will thus all beV turned together toward the right and `rotation will be continued until the tumbler 12 has been turned to a position te position thereduced portion of its key-'hole passage 15 in registry withthe slot 19jof the bearing sleeve 17. Y y Y Y about the yedge portion of the settingbloek will have to be watched so thatturningthe block to theV rightcan be stopped whenthe proper number has been brought into a posio tion above theL marker carried vby the housing 1. After the tumbler 12 has been properly set.,y the block will then be turned to the left and will be turned until'the pinlV of the tumblerlO has madea complete revo-- lution and brought into engagement with ,theV 1,25y pin of the tumbler 11. Continued rotationv ofthe block. toward theleft will then-move the tumbler 11 toward the'left until there-A duced'portionofthis tumbler is moved into o position to register with the 'slot 19. of the 130 Of course, the numbers ,marked .11S-K 'aglutina 'bearing` sleeve. The bearingblock will then thus permit of 'their' being'ffrictionally held inthe set position. VVith-the tumblers all inA the-proper position, the 'key' can then moved longitudinally to the pos'itionsh'own in Fig. 2, with the lugs '30 moved vout of the pockets'and into the'reduced portions ot the key-hole passages 15. The lugs 33-vvill noi'v be in engagement with the switch and When the key is turned, the switch Willbe moved to the adjusted position. lVhen the key 'is turned, the lugs 30 move upinto the-notches or recesses 2O of the bearingsleeve and thus rotary movement of the key beyond a desired amount is prevented. VVit-h the switch turned on and the lugs 30 of the-key positioned'in the recesses 20, the keycannot be moved out of engagement with the switch.

' Akay slipping out of engagementwith theV switch. Vhen it is desired to turnftheV `switch oli', the key is simply turned back toV It should be further noted that when the key is turned,` the tumblers Will also be turned due to the fact that the lugs 30 of the key are positioned in the reduced portions of the key-hole passages of the tumblers. Therefore, the combination cannot becomev scattered and further there is no vdanger of the thev original position. The key can then ,be drawn outwardly until the 'block 31V is or more lof the pins 21.
